I don't really understand why everyone is so quick to advocate checking the flop. I assume you are checking with the intent of raising any bet behind you? Thats a powerful play and will undoubtedly define your hand pretty clearly. I think a better line is bet/3bet. Someone is bound to have hit that flop, and I think that there is a good chance that if you lead like 1/2 pot, someone will come over top. Also, no one will put you on a hand as strong as yours if you lead, as most players are apt to slowplay flopped monsters. IMO, leading is much more deceptive.
